IMPROVEMENT IN GHEESB VATS.

SPECIFICATION- To ALL WHOM IT MAY CONCERN-z invented a=new and usefulImprovement in Cheese Vats; and I do hereby declare that the followingis a full and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereonz,

My invention consists in combining with a cheese vat and its furnace,pipes for supplying the vat with water which, prior to entering the vat,has traversed a pipe which is arranged around on the inside wall of theheating chamber of the furnace, said vat being provided with waste pipesand gauge, and the supply pipes with suitable valves for regulating thesupply and flow of water to the vat; said cheese vat, its furnaces, andthe pipes, gauge, and valves connected therewith, being'constructed,arranged, combined,' and operating in the manner hereinafter described.V

To enable oth ers skilled in the art to make and use my invention, Iwill proceed to describe its construction and operationi. In theaccompanying drawings, which form part of this specifieation- Figure 1represents a perspective view of the furnace, with a portion of the wallbroken out to show the arrangement of the pipes connected with it andthe cheese vat.

Figure 2 represents a transverse section of the furnace pipes and vatwhen out through at the linemarked 8, in fig. 1. v

Figure 3 represents a perspective view of the cheese vat. I

Figure 4 represents a perspective view of a fire dog or grate bar, whichis used in connection with the furnace when wood is used for fuel. i p

In the drawings, Arepresents the furnace, which is provided with a firechamber, 13, and stack, D, and maybe constructed of stone, brick, orother suitable material. In the stack, D, is placed and pivoted adamperor valvefx, so arranged that it can-be set at any suitable anglefor regulating the draught of the furnace. The fire chamber, B, isprovided with a fine door, G, and a fire dog or grate bar, e, which isprovided with a number of openings marked 2'. This fire dog or grate baris placed across the fire chamber B; (asis shown in figs. 1 and 2,) andis used for the purpose of holding the wood used for fuel up ofi' thebottom of the fire chamber, to admit the free access of air to the fire.The advantages of this f fire dog or grate bar are 'twofold: first, itholds the wood up of the-bottom of the fire chamber; second, by means ofthe openings 2' it distributes the air evenly to all parts of the fire,which are advantages that will be apparent to all who use wood as afuel.m represents a conducting'pipe or water log, which conveys the waterfrom a spring or reservoir, whichspring or reservoir of water may belocated near the furnace or at a great distance from it, but in allcases, (when a pump is not used,) the spring or reservoir should be atan elevation which is higher than the furnace or vat, so that the. waterwill flow throughthe pipes into-the vat by its own gravity. To the pipeor water log m is attached, at the point marked g, a pipe, f, whichpasses through the wall of the furnace and .then around on the inside ofthe'wall of i the heating chamber, and then passes out through the wallat a point .directly above where it entered; it then turns up andterminates in opening 5, in B. of the vat P, and is provided with avalve, 12, all of which is clearly'shown in figs. 1 and 2, The vat P ismade of iron, and is provided with a lid, R, (as shown in figs. 2 and3,) and is arranged in the furnace so that its bottom will rest on thetile or brick marked 1 and 2, which will prevent the bottom' of the vatfrom sagging down, and will form a series of flues by means of which theheat will be evenly distributed over the entire bottom of the vat.Through the front end of the furnace wall passes pipe, J, provided withavalve, 0. This pipe is secured in the opening 4, in the front end of thevat,'(see figs.

and This pipe and valve is used as a gauge to ascertain when. the vat issufficiently full of water; Thevat V is also provided with a pipe, Z,which is secured to it near the upper edge, and is used for carrying offthe over supply of waste water, and is also used for conducting anysteam or noxious vapor orgas which may gather in the vat when the lid isclosed down. Near the back end of the vat, near the bottom, is placed apipe, K, provided with a valve, S. This pipe is used for drawing. oh thewater from the vat when so desired. This pipe K passes through the wallof the furnace and'is secured to the vat P. I

As the skillful mechanic will, from the above description, and by.reference to the accompanying drawings, readily understand theconstruction and arrangement of the various parts of my improvement, Iwill therefore proceed at once to describe its operation, which is asfollows:

' Having the pipe or water log" m properly connected to a spring orother supply of water, I then open Be it known that I, ALBERT G. Base,of Holland'Patent, Oneidacounty, and State of New York,,ha ve the valven, in the pipe f, so as to allow a small stream of water to flow intothe vat P. I then start a fire in the fire chamber B, and the heat willcirculate under the bottom of the vat through the openings left betweenthe tiles "or bricks 1 and '2, and will rise up in the heating chamberof the furnace, around the sides of the vat, and also come in contactwith the pipe f, and partially heat the water as it flows through thepipe into the vat. The arrows indicate the course of the water throughthe pipe f into the vat P, When the water rises up in the vat and flowsout through the gauge pipe J, I close the valve 0, also the valve n,which will cut oh the flow of water into the vat. When I desire to drawofi all of the water from the vat, for the purpose of cleaning it, orfor other cause, I open valve S, and let it flow out through pipe K.When'the temperature of the water in the vat rises above the degreedesired, I adjust. the dampera: in the stack, so as to shut off thedraught of the furnace. I then allow the water to flow into thevat'through the pipe f, opening the valve S, so that an equal amount ofthe water will flow out from the vat through the pipe K. This willreduce the temperature of the water in the vat to the degree desired. Itwill readily be observed that by the above arrangement of parts I cancontrol and hold the temperature of the water in the vat to the degreedesired, which is a very important thing in the process of makingcheese. The manner of operating and manipulating the milk in connectionwith the vat is performed in the ordinary manner. i

Having thus described the nature, construction, and operationof myimprovement, what claim as of my invention, is- I v i I i I 1. Thecombination of the pipes m, j, J and K, with the, vat 1?, said pipes andvat being constructed, arranged, combined, and operating substantiallyas herein described.

2. The combination of the abovewith the furnace A, the heat chamber ofsaid furnace being provided with tiles or bricks, 1 and 2, for thepurpose of supporting the bottom of the vat,,and for distributing theheat evenly through all parts of said heat chamber, as herein describedand set forth.

3. The fire dog or grate bar e provided with openings 2', when used inconnection with a furnace combined with a cheese vat, as hereindescribed and for the purposeset forth.
